Jeff Masters, a meteorologist and a co-founder of Climate Underground, a web-based information service, says the rationale extra temperature information usually are not overturned is as a result of the method is just too time-consuming. A working example, he mentioned, is that an effort to reanalyze each named Atlantic storm since 1851, which started 20 years in the past, has up to now reached solely the 12 months 1965.

“There are a whole lot of temperature information within the U.S. alone that will not survive a re-analysis,” Dr. Masters mentioned. “Essentially the most well-known of those is the world-record hottest temperature in historical past of 134 levels Fahrenheit in 1913 in Loss of life Valley.”

Two excessive climate consultants, William T. Reid and Christopher C. Burt, have argued on the Climate Underground website that the 1913 studying was “not doable from a meteorological perspective,” partially as a result of it was not according to different observations made in that a part of Loss of life Valley over the identical week. They are saying the person who recorded the temperature, at Greenland Ranch in California, seems on reflection to have “knowingly or inadvertently” exaggerated the studying, and that he might not have even been current on the time.

However Randall Cerveny, who leads the World Meteorological Group’s efforts to analysis and confirm international climate information, mentioned in an electronic mail that the 1913 studying was nonetheless acknowledged because the “hottest temperature recorded for america and for the world.”

Dr. Cerveny, who teaches geographical sciences at Arizona State College and labored with Mr. Burt to debunk the 1922 Libya file, described the analysis on the 1913 Loss of life Valley file by Mr. Burt and Mr. Reid as “conjectural, not new proof.” He added that the U.S. Local weather Extremes Index, a NOAA venture, has additionally opted to not examine it.

“We don’t dismiss information with out substantial proof proving their inaccuracy,” he mentioned.

As for newer Loss of life Valley information, Dr. Cerveny mentioned the W.M.O. was nonetheless making an attempt to confirm a 129.9-degree studying from that space on Aug. 6, 2020.

If confirmed, it will be the third-highest temperature ever recorded on Earth and the second-highest in america. However Dr. Cerveny mentioned the investigation is “taking some time” as a result of his group has been testing the temperature sensor that made the studying.
